Deep-water circulation is a critical part of the global conveyor belt that regulates Earth's climate. The bottom current component of this circulation is hugely significant in shaping the deep seafloor, through erosion, transport and deposition. As a result a great variety of depositional and erosive features are developed, including a range of different drifts, sediment waves, moats, furrows, and abraded surfaces. The Baiona Congress will be focused specifically on processes and deposits related to bottom-water circulation.
